Timezone Converter

About this timezone converter

Convert a date and time from one world time zone to another, accounting for each zone's own daylight-saving rules on that specific date. Choose a date and time, pick the time zone it's in and the time zone you want to see it in, and this tool uses your browser's built-in time zone database to compute the equivalent local time — no external service or API required. Use this workspace to prepare a result you can review before putting it to use. All processing takes place on your device, without an account or an upload of your inputs. Check the examples to understand the expected output, read the limitations for the supported scope, and reset the form when you want to start a separate task.

How the timezone converter works

Uses the Intl.DateTimeFormat time zone database built into your browser to find the UTC instant matching your entered wall-clock time in the source zone, then formats that same instant in the destination zone.

Limitations & privacy

Limited to a curated list of common time zones rather than the full IANA database. Results depend on your browser's built-in time zone data; a time entered exactly during a daylight-saving transition hour can be ambiguous.

Inputs and results stay in this browser. Only tool identifiers are stored for your recently used tools. You can clear that history from the directory.
